Abstract: A compound semiconductor device of this invention has first and second surface protective films (24, 26) on active region layers (14, 16a, 16b) of a predeter­mined conductivity type. According to a method of fabricating this compound semiconductor device, active region layer (14) of the predetermined conductivity type, for example, N-type, and N⁺-type active region layers (16a, 16b) are formed on GaAs substrate (12) having a semi-insulating property, latter layers (16a, 16b) being adjacent to the former layer (14). Gate electrode (18) is formed on N-type active region layer (14) in Schottky contact therewith, and source electrode (20) and drain electrode (22) are formed on N⁺-type active region layers (16a, 16b) in Ohmic contact therewith. Phosphate-silicate-glass layer (24) containing phosphorus is deposited as a first surface protective film on N-type and N⁺-type active region layers (14, 16a, 16b) and electrodes (18, 20, 22) to protect these active region layers. Silicon dioxide film (26), which does not contain phosphorus, is deposited as a second surface protective film over layer (24) to protect N-type and N⁺-type active region layers (14, 16a, 16b). Then layer (24) containing phosphorus and layer (26), containing no phosphorus, which are deposited on individual electrodes (18, 20, 22), are removed.

Abstract: L'invention concerne un dispositif de mesure d'une grandeur physique, par exemple d'une force (A), qui délivre un signal de sortie (Vs) dont l'amplitude est représentative de la valeur mesurée. Le dispositif selon l'invention comprend un premier oscillateur (1) comportant un résonateur (3) sur lequel est appliquée la force à mesurer (A), cet oscillateur délivrant un premier signal alternatif (S1) dont la fréquence dépend de l'intensité de cette force, un deuxième oscillateur (2) fournissant un deuxième signal alternatif (S2) ayant une fréquence qui est déterminée par l'amplitude du signal de sortie (Vs), une porte OU EXCLUSIF (20) recevant le premier et le deuxième signal, et un filtre passe-bas (21) délivrant, en réponse au signal fourni par la porte (20), le signal de sortie (Vs). L'amplitude de ce signal de sortie dépend de l'écart de phase entre le premier et le deuxième signal, et elle constitue une mesure de l'intensité de la force appliquée (A). Ce dispositif peut avantageusement être utilisé lorsque le résultat de la mesure doit apparaître sous forme analogique.

Abstract: A drum brake assembly has brake shoes (2) and (3) within a rotatable drum (1). The shoes (2) and (3) are displaceable to effect braking by an hydraulic ram (7) and free ends (9) of the shoes react against an abutment (10). This reaction is effected through a layer of viscoelastic damping material and metal plate laminate (110) which may be carried by either the brake shoes or the abutment (10). The viscoelastic layer may be bonded between steel plates and secured by a spring clip to either the brake shoe or the abutment (10). Alternatively the viscoelastic layer may be bonded to the abutment (10). The laminate (110) can be accommodated within a recess in the abutment (10). 
     The provision of the viscoelastic layers through which the brake shoes react on the abutment (10) alleviates the development of noise or squeal during use of the brake assembly.

Abstract: Crosslinkable thermoplastic adhesive composition exhibiting, inter alia, the advantage of being oil-permeable, permitting its use in many fields, in particular in the field of adhesive bonding to greasy sheet metal. The adhesive composition according to the invention is based on hydroxytelechelic polybutadiene and a mixture of diisocyanate compounds. It contains, per 100 parts by weight of hydroxytelechelic polybutadiene, a quantity of tolylene diisocyanate and a quantity of isophorone diisocyanate such that the ratio of the total number of isocyanate functional groups of the composition to the total number of hydroxyl functional groups of the composition is between 0.90 and 1.30. The ratio of the number of the isocyanate functional groups contributed by tolylene diisocyanate to the number of isocyanate functional groups contributed by isophorone diisocyanate is between 0.1 and 2. The catalyst employed is chosen from the group consisting of tertiary amines and organic lead or tin salts and is introduced into the composition of the mixture in a proportion of 0.1 to 1% by weight in the case of a tertiary amine and in a proportion of 0.01 to 0.1% by weight in the case of a metal salt.

Abstract: Dispositif de blocage terminal pour fermetures à glissière, permettant de bloquer de manière libérable l'extrémité d'une première rangée de dents dans une douille terminale fixée à l'extrémité d'une deuxième rangée de dents. Le dispositif comprend un organe de verrouillage monté de manière à pivoter sur la douille terminale et un élément d'engagement situé à l'extrémité de la deuxième rangée de dents. Lorsque l'extrémité de la première rangée de dents est introduite dans la douille terminale pour fermer la fermeture à glissière, l'organe de verrouillage et l'élément d'engagement sont amenés à s'engager l'un dans l'autre et maintenus dans la douille terminale. Afin d'ouvrir la fermeture à glissière, l'organe de verrouillage est poussé manuellement, ce qui provoque le dégaement des extrémités des rangées de dents et permet à l'extrémité de la deuxième rangée de dents de sortir de la douille terminale.
